(CNN) -- The suspect in the failed Times Square car bombing is a Pakistani who became a naturalized U.S. citizen in April 2009 and had not been on national security radar.

Faisal Shahzad, 30, of Bridgeport, Connecticut, was arrested Monday night at John F. Kennedy International Airport in New York as his flight to Dubai was about to take off, law enforcement officials said.

Shahzad had traveled to Dubai before. He took a flight there in June 2009 and stayed out of the United States until his return on Feb. 3, officials said.

A woman who said she had lived next door to Shahzad in Shelton, Connecticut, told CNN on Tuesday that the man she knew didn't say much and claimed to work on Wall Street in New York.

"He was quiet. He would wear all black and jog at night. He said he didn't like the sunlight," Brenda Thurman said.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungleā€”as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
